HILMAN M. PAPST, OF SAN FRANCISCO, CALIFORNIA.

APPARATUS FOR MANUFACTURING GAS.

SPECIFICATION formingpart of Letters Patent No. 710,336, dated September 30, 1902.

Application filed December 17, 1901. Serial No. 86,325. (No model.)

To all 111700772 it may concern.-

Be it known that I, I-IILMAN M. PAPST, (having declared my intention of becoming a citizen of the United States,) residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Apparatus for Mannfacturing Gas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in manufacturing gas, which .gas may be used either for illuminating or heating purposes.

My apparatus is designed especially to make water-gas from the heavy California oil,which is now being produced in large quantities. This water-gas can then be used directly for heating purposes, or, preferably, it may be enriched and used'for lighting purposes.

The object of my invention is to efiect increased economy and efficiency in an apparatus for water-gas; and with this object in View my invention consists in the construction and combination of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure l is a longitudinal section of my apparatus, taken on the line 1 1 of Fig. 2. Fig. 2 is a crosssection thereof, taken through the center of one of the two super-heaters. Fig. 3 is ahorizontal section taken on the line 3 3 of Fig. 2; and Fig. 4. is a cross-section of the top of my apparatus, showing the means whereby the same may be used reversibly.

a represents a rectangular base or shell divided into two equal parts by the wall cl, made of fire-brick; In fact, the whole structure is built of refractory material. Over each of the chambers formed in the shell a, by the partition d are arches f g, and a passage 6 connectsthe two chambersthus formed atthe rear of the shell a. On the rear part of the shell a are mounted two parallel cylindrical superheaters 19 andc, the lower part of which is filled with checker-work or refractory material.

h and 2' represent valved oil-injectors, of the usual type, discharging into the chambers below the arches f and g, and j and 7; represent valved air pipes delivering into the same chambers.

Arches l and m, about half-way up the cylindrical shells Z) and c, are sprung across said shells, leaving chambers below, into which the valved oil-injectors n 0 and the valved air-pipes p and q deliver. Above these arches in each of the shells there is another checkerwork, of brick, which, however, does not reach quite to the top of said shells, leaving chambers r and s,vinto the latter of which a valved pipe i for the; inlet of superheated steam enters.

u'and u represent pipes through which waste gases may be discharged into the stack, and w and ac represent the usual swinging stack-valves.

y is a pipe which connects with the chamber 0", through which the gas is conducted off to the holder. The shell a is provided with four openings, closed, respectively, by the doors .2, 1, 4, and 5, which doors are held in place by the screws 2, 3, 6, and 7, respectively. Passages 8, 9, 10, and 11 are left in the arches for the free upward passage of gas.

The operation is as follows: Oil is admitted through the pipes 71 and z'and ignited. At the same time air is blownin through the pipes j and 7c. The gases from the combustion of the oil pass upward through the shells b c, and the valves to and w being open waste gases pass through the stack. (Not shown.) After the apparatus has been heated up the oil-injectors h and 2' and air-injectorsj and 7c are closed. The stack-valves w and a; are also closed. The valve in the steam-pipe tis opened and oil is admitted through the oilinjector 0. If the proper degree of heat has been reached in the shell 0, the carbon of the oil admitted through 0 will be disassociated from the other elements in the oil and will be converted into solid carbon or lampblack. The superheated steam in the presence of this carbon will be disassociated, and theresulting gaseshydrogen and carbon monoxide will pass down through the checker-worliin the shell 0, through thepassage 6, around the brick arch'f, into the shellb, which acts as a superheater.

If it is desired to make illuminating-gas, oil is admitted through the injector n, and

the gas is carbu-reted to any desired extent. By adding another steam-pipe, having it doliver into the chamber a", and another delivery-pipe, like the pipe 11 connected with the pipe '1), it is obvious that the apparatus shown can be used reversibly, as shown in Fig. 4:. I have found, however, that after once thoroughly heating up the shells b and c I can go on making either illuminating or heating gas for a long time Without having the heat in said shells come down so low that it is necesessary to blast them up again.

tinuons combustion-chamber is formed, re= generative devices, located over each of said chambers, and inlet-pipes for steam, air and oil, leading into said combustion-chambers and regenerative devices.

3. In an apparatus for manufacturing gas, the combination of a base, a Wall passing partly through said base, forming two chambers united together at the rear, whereby a continuous combustion-chamber is formed, a cupola-like structure located over each of said chambers, each of said structures being divided into two parts, each having checkerwork therein, inlet-pipes for air and oil leading into each of said chambers in said base, inlet-pipes for steam, air and oil, leading into each of said regenerative or fixing structures and outlet-pipes for the product of said apparatus.

In testimony whereof I affix my signature in presence of two witnesses.
